As any tarot reader will tell you, this form of divination is merely a guideline where the reader interprets the probable outcome. Nothing it set in stone.
It is, however, a highly intuitive process and so, while books and charts may come in handy, the only real way to use your tarot cards is by learning what the cards mean, handling them, getting to know them on an intimate, one on one level.
Choosing a deck can be somewhat ominous as there are hundreds and hundreds of decks available. My advice to you would be to choose one that calls to you. Start out simple buy purchasing a deck and instruction guide that appeals to your tastes.
A Tarot deck consists of 78 cards. The first 22 cards are the Major Arcana. These cards have symbolic meanings focused on the material world, the intuitive mind, and the realm of change. The remaining 56 cards are the Minor Arcana, and are divided into four groups or suits: Swords, Pentacles (or Coins), Wands and Cups.
Each of the four suits focuses on a theme. Sword cards generally indicate conflict or moral issues, while Cups reflect matters of emotion and relationships. Coins focus on the material aspects of life, such as security and finance, while Wands represent things like jobs, ambition, and activity.
There are specialty cards as well that do not have nearly as many cards. So do bear this in mind.
Any experienced Tarot reader will tell you that reading cards is an intuitive process. Like any other form of divination, the cards become a focal point for your own psychic abilities. There is any number of different spreads, or layouts, which can be used in a Tarot reading. Some readers use elaborate layouts, while others may just pull out three to five cards and see what they need to see.
One of the most popular layouts is the Celtic Cross method. Other well-known spreads include the Tree of Life layout, the Romany spread, and the Zodiac method. You can also create your own layout.
Sometimes, a card comes up backwards or upside down. Some Tarot readers interpret these reversed cards in a way that is the opposite of the cards right-side-up meaning. Other readers may not bother with a reversed interpretation, feeling that the messages may be incomplete. The choice is yours.
Although you may pull half a dozen cards for someone that indicate all kinds of gloom, doom, and destruction is headed their way, try to keep things positive. If you believe some sort of illness is coming, or their marriage is in trouble, DONT freak out your client by being negative. Instead, remind them that things can change at any time, based upon the decisions they choose to make in life.
Read for anyone and everyone who will let you and dont be afraid to tell people what you see.
